To all whom it may concern:

, Be it .knownthat I, MARK -WAL'1ON, a citizen of the United States, and a resident of Ullin, in the county of Pulaskiand' State of Illinois, have invented a new and useful Improvement in Antifreezing Pumps, of

which the following is a-full, clear, and eX- act description. Y

. My invention relates to improvements in anti-freezing pump, and it consists "in the combinations, constructions, and arrangements herein described and claimed.

An object of -my invention is to provide an anti-freezingpump which has novel means for permitting the water in the .pipe to How back into the well to prevent the freezing of the water in, the winter time as stated, this water is led back into' the well instead of draining into the groundas is usually the case. Thisxprevents the ground adjacent to the pump from becoming sloppy. I

A further object of my invention is to provide a device of the character-described to flow back into the Well is adapted to retain th water disposed between the pump cylinder and the water in the Well, this water being used as a prime for the next pumping operation.

A further object of my invention is to provide a device of the character described which is simple in construction and which may be readily attached to a standard pump, thus converting the standard pump into an anti-freezing pump.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing, forming part of this application, in which Figure 1 is a side elevation of the device as shown operatively applied to a pump,

Figure 2 is an enlarged detailed section of the device, and

Figure 3 is an enlarged sectional view of the valve.

In carrying out my invention, I make use of a pump 1 which has a standard pipe 2 in communication therewith and which is provided with a pump cylinder 3. The cylinder is disposed a suflicient distance below th surface of the ground so as to prevent Application filed A ri 9,

freezing. of the water within the cylinder. By' operating theahandl'e 4, theTpistom -not shown, within the cylinder 3 .is actuated and sucks the water through thexscreen' 5 and forces it out ,through'thevmouth Got the pump. I i 1' PT My attachment comprises ahyli'nder; n which a float 8-is slidablydisposed. he cylinderis placed in communication}.rwith the pipe 2 ,bymeans of-pip'es 9, 10,; and; :11. It will be notedfro'm Figure 2 that th'e pipes '9 and 10 extend above the cylinderifiran'd communicate .withthe portion of. the-,pipe"2' that is disposed betweenthe, cylinder 3 and the pump '1. The pipe 1:1 isp'laced in com-- munication with the pipe 2 that depends from the cylinder 3. The fioaty-8w is pro- I .vided with a guide '12,; the lower end-"of this guide being provided with a needle-valve 13. The hottomof the cylinderv 7 has a conical shaped recess 14 that is" adapted to. receive the valve The-recess 14 is inv communicationavith the interior of the cylinder. 7 and with thepipell. T: From the foregoing":descriptionofuthe 19 adapted to raise the float 8 so as to open the valve 13 and permit this water to drain through the pipe 11 and back into the pipe 2. In this manner the water disposed in the section of the pipe 2, that is positioned between the cylinder 3 and the pump 1, is drained off and is returned to the well and is not drained into the ground as is usually the case. The pump 1 may be operated in the ordinary manner and suck the Water through the screen 5 and force it out 1 through the outer opening 6 of the pump. The pipes 9, 10, and 11 are so small that they will not interfere with the normal operation of the pump. As soon as the pumping operation is stopped however,.the water disposed between the cylinder 3 and the pump 1 drains through the pipe 10 and flows into the cylinder 7 The pipe 9 is an air pipe and permits the water to drain through the pipe 10. The cylinder 7 retains this drained water for a short time, due to the fact that the needle valve 13 is closed. As soon as the water has risen to a predetermined level within the cylinder 7 the valve 13 will be opened and will permit the water to drain through the pipe 1.1

and back into the ell. The Water will continue to-fiowback into the well as long as the valve is open. The valve will seat, however, before all of the water. in the cylinder 7 drains therefrom. The closing of the valve 13 retains the water in the pipe 11 and the portion of the pipe 2 disposed below the pump cylinder. This water is used for priming when the pump is again operated.

The device is attached to the pump portion and thelatter is then disposed in the ground andafter the pump has been driven into place, the earth is filled around the attachment, asshown-in Figure l to prevent the water inthe cylinder 7 and cylinder 3 from freezing. The cylinder 7 and cylinder 3 aredisposed a sufficient distance below the surface of the ground soas to obviate any freezing ofthe Waterwithin the cylinders. The device is simple in operation and pro vides a novel means for draining the water from the pipe2 disposed adjacent to the surface of the ground, and at the. same time retaining a suflicient amount of water'to be used as a prime for the next pumping operation.
